Abstract (en)

[origin: EP2258470A1] A method of manufacturing an affinity particle includes a step of reacting a particle having a reactive functional group on a surface thereof with a ligand having a functional group having a reactivity with the reactive functional group to bond the ligand to the particle, and a step of reacting the particle to which the ligand is bonded with a surface modifying agent having a functional group represented by a general formula of: (wherein each of R 1 , R 2 , and R 3 is independently an alkyl group whose carbon number is 1 or more and 6 or less, m is an integer of 2 or more and 6 or less, and n is 1 or 2.) and a functional group having a reactivity with the reactive functional group to bond the surface modifying agent to the particle to which the ligand is bonded.
